About this 3D model
Here is a small container to keep picks in. The lid swivels open on a pin and then snaps back into place. There are two versions of the pin--one has a slightly larger diameter than the other one--because I've found that not all my filaments print out to exactly the same size. The pin should fit snugly enough that pliers or a hammer tap is needed to seat it completely. A raft is strongly advised for printing the pin. Otherwise no supporting material is necessary. There is also a small hole in the top for stringing it on a cord if desired.
